제목 | Mechanically and Electronically Tunable Conductive Antifouling Hydrogel Based-Visible Light-Responsive Carbon Dot for Wireless Pressure-Strain Sensor |
초록 | Herein, a wirelesspressure and strain sensor based on a conductive hydrogel coated with carbondots (CD) for mechanically adjustable antifouling behavior was elicited byvisible light. The conductivity, pressure, and strain sensitivity of thehydrogel were controlled by switching of hydrophobic-hydrophilic transformationof the CD components which controlled the antifouling effect by mild mechanicalforces enabling the cells to be squeezed out from the hydrogel. The photocatalyticactivity of the CDs changes in swelling behavior thereby increasing themobility resulting in the 4-fold higher conductivity, 158 % enhanced mechanicalstrength, 231% improving stretchability, which intensifies the pressure andstrain sensing response. The antifouling phenomenon engaged physicaldeformation associated with the changes in the electrochemical behavior of thehydrogel which was monitored by wireless sensing. |
